• Maintained Django APIs and MySQL db powering ~150 write requests / second (+ EventBridge triggers after insert) - when hundreds of offline apps resync at once; with worker pool via Lambda auto-scaling. Images uploaded to S3 synchronously with 3 staggered retries.
• Built a server-side pipeline that turns campaign form templates into on-device redaction descriptors (SIFT keypoints + field geometry), so canvassers’ phones can redact PII and verify fields are filled out.
• Optimized SQL queries and aggregation endpoints for analytics dashboard, doubling data output while maintaining speed and adding search filters.
• Centralized logging through Firebase and wrote BigQuery monitoring to compare with SQL data for integrity and usage.

AI Annotation Interface & APIs

• Created custom Node-Red modules for configuring cameras and communication with on-prem tools and cloud APIs.
• Implemented API for motion detection using Structural Similarity, to expose 19 OpenCV filter options to training interface, to manage photo training data and find tagging anomalies.
• Built entire front-end annotation tool with zooming, version controls, infinite class nesting.

Workstation Guidance

• Developed workstation guidance system for factories to configure assembly instructions with QA and computer vision assistance, dockerized to deploy across a local network of factory computers.
• Built bi-directional persistent secure WebSocket connection for constant communication with Node-Red service and FlexibleVision as a whole.
